What is the market size of the torque sensor


Torque sensor from Bosch for new steering systems

Electrically driven systems for steering assistance will replace the currently common solutions based on hydraulics or electrohydraulics in the next few years.

In order to be able to implement this servo function and other planned functions, the control unit of the steering system needs precise information about the steering commands. Bosch is therefore developing sensors that electronically record the required data on angle of rotation, direction of rotation and torque.

The first small cars with electric power steering (Opel Corsa) are already on the market. More powerful systems are increasingly enabling use in higher vehicle classes. Servo systems operated in this way primarily lead to reduced fuel consumption. The electronic control of the systems, however, places high demands on the sensors; for the first time it needs information about the torque.

Opel Corsa:

The electrically assisted power steering works depending on the speed, so that the power assisting the steering is only generated when it is needed. You can feel low steering forces when maneuvering in city traffic and when parking. This power steering also ensures good road contact and is fuel-efficient on long journeys.
